Will always-on wearables displace the smartphone as the dominant personal computing interface in the AI era?

The dominant interface will be an always-on wearable processing multimodal tokens — cameras for visual input plus an earpiece that whispers feedback and can be spoken to for later action

Sensors (seeing, listening) plus effectors (speaking, remembering) let the device read things like body language and follow up on your behalf

The phone will look radically different — an AI device may still contain a phone app, but the phone app is the least interesting part and everything else will be transformed into an extension of your brain

A constantly listening and watching device that pages experience to memory for later retrieval is far more valuable than telephony

Face-mounted computing like VR is the wrong direction because it disengages people from the world rather than connecting them to it

He realised he doesn't want to strap a computer to his face; he wants to be more engaged with the world, not less

The phone has passed the peak of its importance in people's lives and will be displaced by other interfaces such as implants, smaller devices, or a voice operating system for LLMs

Its run is over and new LLM-native interfaces will take over, though the replacement device may not have been invented yet

The smartphone will remain the primary computer mediating conversational experiences, with glasses and earbuds as complements that reduce screen time rather than replacements

Fifteen years of consumer electronics attempts to replace or augment the phone have failed; the phone is so good at so many things, everyone already has one, and it has removed the market for almost every other consumer device

45:26 Smartphone remains primary with glasses and earbuds as complements not replacements

Always-with-you AI requires a lightweight wearable plus a separate compute 'puck', so phone-like devices will not disappear

You can't put huge batteries or heavy compute into glasses, AirPods, a pendant or a brooch, so you'll need a lightweight connection to a device you offload compute to — and there's no reason that device shouldn't have a touchscreen
